Field of application
The FT 6060 fresh-air laboratory heating oven has been designed as an item of laboratory
equipment to be used for heating items and materials in the laboratory.
The items or materials to be heated in batches may bear traces of combustible liquid solvents.
These combustible solvents may belong to danger classes II A and II B, temperature classes T 1,
T 2, T 3 and T 4.
Heat treatment of samples or materials with operating temperatures of
5° above the temperature of the fresh air up to 70 °C (T 4)
1)
or
5° above the temperature of the fresh air up to 105 °C (T 1, T 2, T 3)
1)
e.g. for drying, ageing, gelling, concentration, analysis, fusing, oxidizing, reducing,
preheating, etc.
The quantity of combustible solvent introduced into the inner chamber is only restricted by the
maximum loading volume of the processed items or material and the loaded weight.
When loading the items or material to be processed, make sure that sufficient clearance is
maintained between the inside walls of the inner chamber and the loaded articles and between
the individual items in order to maintain an adequate free cross section of flow for the current of
air passing through the chamber.
This prevents any local concentration and ensures an even heat rise and penetration of the
loaded articles.
All items must be placed in open containers before being loaded into the chamber.
Refer to the chapter on OPERATION for an example of loading.
The unit has been designed for installation and operation in the following fields:
Laboratories, e.g. in the commercial or industrial sector, schools, universities, hospitals and
biology.
Operating areas subject to fire risk as defined by DIN VDE 0100 Part 720.
Refer to the chapter on TECHNICAL DATA for information about the protection class.
The heating oven has been designed for continuous use.
Protective gloves, goggles, etc. must be made available to the operator.
Zone 1 explosion protection measures have been implemented inside the internal
chamber. The unit must not, however, be used in intrinsically hazardous areas.
The unit has also not been designed to dry hazardous dust or explosive substances.
1)
For a fresh-air temperature of > 20 °C and a nominal voltage of 230V, the max. working
temperature will not be reached if the temperature of the fresh air is lower than this and/or a
lower voltage is used.
